Need help with deinterlacing.

I've never used deinterlacing for any of my amv's but now I've decided to try it since my last amv had some parts where the lines got really jagged when I slowed the video down.

My computer has problems with avisynth (it can only open 1 avs file at a time) so I've ripped the episodes from dvd and converted each episode to Huffyuv. Then I've used virtual dub to deinterlace the clips and bring them into priemere.

I just wanna make sure this is a decent process? Should I be doing it another way?

You should be using AviSynth to deinterlace.

Look here: http://www.animemusicvideos.org/guides/ ... index.html

Right-click on each affected clip, <b>uncheck</b> the box that says "Deinterlace when speed is below 100%", and see if that helps. That's often the cause of such jagged lines (SO many of these in the videos on the Otakon tapes...).

Unfortunately, I don't know of any way to do this to all the clips in the project... unless selecting them all works. (I expect it won't because they'll have different speeds, but if it does, then great.)

Argh. Append to previous post: All this is assuming you have Adobe Premiere, 6.5 or lower (Premiere Pro replaces the deinterlacing with something much more useful: <i>frame blending</i> the speed changes. Or maybe that's just when you're working progressive -- I never work interlaced, so I wouldn't know.)
